Application filed April 10, 1916. `Serial N0. 90,153.

To allfwtomit may concern.' p

Be it known that I, .NICHOLAS STOCK, a citizen of the United States, and residing in Kingston, inv Ulster county and State of New York, have invented certain new-and .useful Improvements in Chair-Tips, of which the following isa specication.

The present invention relates to improvements in chair tips, and particularly an im-A proved tip which will be readily removable and changeable, and highly resistant to wear and tear. An object of the invention is to provide such a device in which the tip portion 'is welded upon the metal attaching portion in such manner that it is impossible for the tip to break ofi' or to be rotatably moved with respect to the attaching member. A further object is to provide such a Vtip in which the metal parts are so constructed as not tomar the finest oors, should the rubber tipportion become worn away without being detected.

With these and other objects in view, my invention is shown in the accompanying drawings, and will be hereinafter more fully described with reference thereto and finally pointed out in the claim.

In the accompanying drawings:

Figure 1 is a-perspective view alongthe lower end of a chair leg with my improved tip attached thereto,

Fig. 2 is a vertical sectional view thereof,

Fig. 3 is a view of the tip partly in section,

Fig. 4iA is a View of the attaching screw partly in section and showing in dotted lines the relation of the screw socket,

Fig. 5 is a side view of the screw socket,

Fig. 6 is a sectional view taken on-the' line 6-6 of Fig. 4c, and

Fig. 7 is a sectional view taken' on the line 7--7 of Fig. 5. f v

Similar reference characters indicate cor= responding parts throughout the several iigures of the drawings.

Referring to the drawings, my invention comprises an attachment member 10 screw threaded at its end 1l and at its other end provided with a bowled head 12 having a plurality of openings 13 therethrough.4 A rubber tip 14 is moldedupon the ,headed end of the screw as clearlyshown in Figs. 2 and 3, the rubber extending throughthe openings 13 of the head. rIhis construction f positively prevents any loosening or rotary motion. of the tip upon the screw.y The bowled head retains therubber intact until entirely worn away, and when'worn to such an extent that the head becomes exposed, its surface is such that there is no possibility of marring the floor. or tearing the carpet.

A socket member l'interiorly threaded at its upper end 16 is embedded in a hole 17 bored into the end of the chair ,leg 18, the outer sides of 'the socket being' fluted as at 19 to prevent any turning motion thereof. The lower end of theJ socket is `flared outwardly as at 20 and is countersunk in the chair leg as clearly indicated in Fig. 2.

I claim: An improved furniture pad comprising an attachment member having a shank, a convex concave circular head at one end of the shank,-

integral therewith and coaxial thereto and flaring from the shank and at its interior side concave to the shank to form a bowled circular head, and a single piece cushion member molded upon said end of the shank centrally and coaXially with the shank and bowledcirclilar head, completely inclosing and covering all parts of said circular head,

said circular head having substantially cir-l cular openings therethrough arranged about the shank and spacedinwardly from the rim of the head, Said rim being continuous and uninterrupted sind seid openings hav- In testimony thlat I claim the foregoing ment from vthe head, the exterior side of said ing annular Het Walls II whereby to prevent as my invention, I have signed my naine in 10 cutting of said cushion 'and to support said presence of two subscribing Witnesses. cushion from vertical Vand lateral displace- NICHOLAS STOCK! lbowled circular head and the tip end of the Witnesses: vshank being on the saine contlnuous un- G.
